Usage share of web browsers

The most used web browser by country in 2020

The usage share of web browsers is the proportion, often expressed as a percentage, of visitors to a group of websites that use a particular web browser. For example, when it is said that Chrome has 37% usage share, it means that some version of Google Chrome is used by 37% of visitors who visit a given set of sites. Web browser usage share varies from region to region as well as through time.

Accuracy

Measuring browser usage in the number of requests (page hits) made by each user agent can be misleading.

Overestimation

Not all requests are generated by a user, as a user agent can make requests at regular time intervals without user input. In this case, the user's activity might be overestimated. Some examples:

• Certain anti-virus products fake their user-agent to appear to be popular browsers. This is done to trick attack sites that might display clean content to the scanner, but not to the browser. The Register reported in June 2008 that traffic from AVG Linkscanner, using an IE6 user-agent, outstripped human link clicks by nearly 10 to 1.
• A user who revisits a site shortly after changing or upgrading browsers may be double-counted under some methods; overall numbers at the time of a new version's release may be skewed.
• Occasionally websites are written in such a way that they effectively block certain browsers. One common reason for this is that the website has been tested to work with only a limited number of browsers, and so the site owners enforce that only tested browsers are allowed to view the content, while all other browsers are sent a 'failure' message, and instruction to use another browser. Many of the untested browsers may still be otherwise capable of serving the content. Sophisticated users who are aware of this may then 'spoof' the user-agent in order to gain access to the site.
• The browsers Chrome, Safari and Opera will under some circumstances fetch resources before they need to render them, so that the resources can be used faster if they are needed. This technique, prerendering or pre-loading, may inflate the statistics for the browsers using it due to pre-loading of resources which are not used in the end.

Underestimation

It is also possible to underestimate the usage share by using the number of requests, for example:

• Opera and Gecko-based browsers since Firefox 1.5 use fast Document Object Model (DOM) caching. JavaScript is only executed on pageload from net or disk cache, but not if it is loaded from DOM cache. This can have an impact on JavaScript-based tracking of browser statistics.
• While most browsers generate additional page hits by refreshing web pages when the user navigates back through page history, some browsers (such as Opera) reuse cached content without resending requests to the server.
• Generally, the more faithfully a browser implements HTTP's cache specifications, the more it will be under-reported relative to browsers that implement those specifications poorly.
• Some ISPs, mainly mobile network operators, have begun stripping the user agent strings.
• Browser users may run site, cookie and JavaScript blockers which cause those users to be under-counted. For example, common AdBlock blocklists such as EasyBlock include sites such as StatCounter in their privacy lists, and NoScript blocks all JavaScript by default. addons.mozilla.org reports 15.0 million users of AdBlock variants and 2.2 million users of NoScript.

Differences in measurement

Net Applications and W3Counter use unique visitors to measure web usage. This has the effect that users visiting a site ten times will only be counted once by these sources, while they are counted ten times by statistics companies that measure page hits.

Net Applications also uses country-level weighting to correct for bias caused by variation in sampling rates across countries.

Historical usage share

StatCounter (July 2008 to present)

Usage share of web browsers according to StatCounter.

StatCounter statistics are directly derived from hits (not unique visitors) from 3 million sites using StatCounter totaling more than 15 billion hits per month. No weightings are used.

Desktop and mobile browser usage

StatCounter reports desktop (including laptop) and mobile browser share separately. For consistency, each desktop browser share has been reduced by multiplying it by the current overall desktop share versus mobile. Similarly, mobile browser shares have each been multiplied by the overall mobile percentage. This avoids having greater than 100% usage share when combining mobile and desktop.

Net Applications (2004 Q4 to present)

Net Applications bases its usage share on statistics from 40,000 websites having around 160 million unique visitors per month. The mean site has 1300 unique visitors per day.

On 1 August 2009, Net Applications began weighting its raw data based on the number of internet users in the countries concerned, using data from the CIA ; the changes were applied retroactively to older data, starting with November 2007. Quarterly data prior to Q1 2008, is reported with a different methodology compared to quarterly data starting with Q1 2008, so combining these data sets and/or using them as the basis for identifying historical trends could result in flawed information. * Net Applications no longer reports data prior to November 2007 due to this change in methodology.
